How much moisture is acceptable in a wall?

A range of 5 to 12 percent is considered optimal. A reading of up to 17 percent is generally considered moderate moisture and acceptable. Any reading over 17 percent is considered to be an indication of saturation and the need to replace the drywall and to take preventative measures against future moisture buildup.Click to see…

Regarding this, what is an acceptable moisture readings?Generally speaking, for drywall, a safe moisture content (%MC) would be less than 1% MC. Anything above 1% MC in drywall would indicate a level of moisture that could compromise the integrity of the gypsum board. Exterior walls may use a variety of materials, from wooden siding, to vinyl, aluminum, brick, and stone.Secondly, are moisture meters accurate for drywall? The moisture detection range of the meter’s drywall scale setting—a drywall moisture meter should be able to accurately detect very small amounts of moisture (such as 0.1% MC). If testing behind drywall to find a moisture intrusion source, extended-length pins are a must. In this way, how do you check for moisture in walls? To test for moisture inside the walls, start with manual tests and proceed to moisture meters. Look at the wall surface carefully. Push on the wall slightly to see how it feels. Smell the wall to test for moisture. Drill two small holes, about 3/16 inch in diameter and about 1 inch apart, into the wall. Is it normal to have moisture in walls?Homes are prone to problems with condensation during the colder months. A large temperature difference between the air outside and the air inside your home encourages condensation on surfaces like walls and windows. This excess condensation can cause wet walls, encouraging mold growth and drywall stains.
